'The diagonal shafts and each terminatesin a appropriate direction. Onthe hub of sector 6 is a stud b that stands in the path of a cam-pin 71.that projects radially from shaft H. When the door reaches the end ofits run this cam-pin (which by virtue of the aforesaid reducing gearmakes less than one complete turn for each door stroke) has revolved farenough to strike stud Zr and turn the sector 6 back to its neutralposition from which position it had beenmoved by the operator to startthe door on'its run. Since this engagement of the cam-pinwith stud bonlyoccurs at the end of the door run, the sector 6 is free during said runto be turned manually by the operator either to stop or to reverse thedoor. After the cam-pin has brought the sector to neutral, the nextsucceeding movement of the sector will of course be in the oppositedirection, turning the stud 6* away from cam-pin h, to either reopen thedoor if it has been closed or reclose it if it has been opened by thepreceding sector cam-pin has automatically restored to neutral.

' Thedoor-shaft each door orgroup of doors, as appears in the plan viewin Fig. 2. Each shaft will have its own pinion 1* (all pinionscooperating with the single set of bevel gears F and F also its own slipjoint G and its own controller K. Every door, orgroup of doors, cantherefore be operated independently of the other by the one motor whichruns continuously so long as its services are required, its inertiaaiding instead of retarding the The door-shafts H radiate from thecenter of the car to the several doors. In this case doors P and P areworked individually P and P as a group. H include gimbal joints spurpinion S engaging a gear wheel S on the shaft of an ordinarydoor-operating arm T, as is particularly shown in Fig. 3. In that figurethe arm T operated by gear wheel S is jointed at its outer end to slideV on a rod secured to and parallel. with one edge of the door. The doorsP and P are interconnected in a known manner so that the operation ofone will involve the simultaneous operation of the other. Fig. 2 shows Pas the one worked by shaft with P is shown in Fig. 3, the levers R Rconnected to the respective doors being reversely cross-connected by alink R The doors when closed will be locked in the usual wayby the arm Tcoming nearly to a horizontal position in dead-center relation to thedoor. If the door, in closing, encounters an obstruction, the joint Gwill slip until the obstruction is removed. The shaft which works thecam-pin 71, to give it its. function as a disconnector is reduced inspeed with respect to the motor-shaft and displacement which the I 1 l11' will be duplicated for H and its interconnection also with respectto the shaft of the door arm T. Hence although the arm turns less than180 degrees, the cam-pin turns nearly 360 degrees and is therefore aconvenient member to effect in a simple way the automatic disconnectionof the doorfrom the motor at the end of the door run. While some othergiven ratio of time relation between the doorand disconnector might beemployed, this one-to-one relation between door'stroke ratus.
